ABSTRACT

This data analysis was developed in coordination between the St. Andrew Bay Resource 

Management Association’s (RMA) Baywatch Program and the Northwest Florida Water 

Management District (NWFWMD). The objective was to complete an analysis of all 

Baywatch water quality data for the St. Andrew Bay system from 1990 through 2006. 

These analyses are intended to further the Program’s understanding of the St. Andrew 

Bay system and their Baywatch water quality monitoring program. Each of the three 

techniques employed in the analysis of these data were used to provide a distinct look at 

the cumulative data. The statistical summaries provided a thorough description of the 

data that allowed for a careful examination of individual sites. This showed the extremes 

of the variability in the data within each site. The site statistical differences showed intersite variability by monitoring category. This approach provided a depiction of data 

differences and similarities of the two data types, but not differences for the overall data 

(all sites together). The evaluation of the data via percentiles not only showed data 

placement relative to all the data for a given parameter combined, but also represented all 

monitoring categories in the same display. Further examination for select cases of data 

extremes with correlation analysis showed the influence of time on various water quality 

parameters. Although few significant trends were observed, potentially important 

associations of time were found with some parameters. Percentiles and correlation with 

time may prove to be a valuable approach to reveal ecological or system-wide 

importance.

Introduction 

The St. Andrew Bay Ecosystem 

As previously described by Notestein (2007), St. Andrew Bay is a relatively large 

(~69,000 acres) Gulf of Mexico estuary along the Florida panhandle. It is contained 

primarily within Bay County Florida, but includes portions of Walton, Washington, 

Jackson, Calhoun, and Gulf Counties (Figure 1). This highly saline ecosystem contains 

important marine and estuarine habitats including large expanses of seagrasses and salt 

marsh. A high diversity of plant and animal life has been documented in St. Andrew Bay, 

making it a nationally significant bay system (Keppner 2002). Taken together, the St. 

Andrew Bay system is extremely important to the people of Bay County and their 

international visitors. The services this system provides include, but are not limited to, 

the local water supply, world-wide tourism, commercial and recreational fisheries, and 

all manner of water recreation. 

Like many coastal lands in Florida, marked development has occurred in the St. 

Andrew Bay watershed (~732,000 acres). Plans currently exist for unprecedented 

development in this area because of its inherent natural beauty and location. 

Environmental management activities for this system are subject to several private, 

county, state and federal groups.

 Starzinger (2003) described the system well as follows. The St. Andrew Bay 

system has an average depth of approximately 17 feet, and depths as much as 65 feet 

have been recorded. He, like many, found the system unique in several respects. The 

natural tributaries are relatively clean, and several are spring-fed. No major rivers 

terminate in the watershed and therefore sediment burdens are quite low. As a result of 

these conditions, the estuary exhibits high water clarity and high salinity. This is the only 

bay system found along the northern Gulf of Mexico that is both an inland embayment 

and lacks large river system inputs. This creates a unique environment that allows for 

extensive bay-wide beds of seagrass species such as turtle grass (Hackney 1992). 

St. Andrew Bay Resource Management Association Baywatch Sampling Effort 

Since 1990, the St. Andrew Bay Resource Management Association (RMA) has 

maintained and expanded a local water sampling effort. Today 76 sites are routinely 

sampled. Sites are shown in Figures 2 through 8 along with stations for which sampling 

has been discontinued (a detailed station list in provided in the appendix). The RMA will 

continue long-term implementation and coordination of the Baywatch volunteer water 

quality monitoring program. This program was initiated to monitor water quality 

conditions throughout the St. Andrew Bay system. Site monitoring varies with the 

rationale behind the site’s selection. To date, the rationale has supported three major 

groups, paraphrased here as: University of Florida Lakewatch sites (UF), General 

Baywatch monitoring sites (BW), and Seagrass monitoring sites (SG).

 Briefly, the data collected can be summarized as follows. The measurements 

recorded for each station included water depth (ft for UF and BW, m for SG), Secchi disk 

depth (ft for UF and BW, m for SG), water temperature (oC), dissolved oxygen (mg/L), 

turbidity (NTU), salinity (ppt), pH (standard units), chlorophyll a (ug/L), total nitrogen 

(ug/L), and total phosphorus (ug/L). Additional information collected at sites has 

included air temperature, tides, rainfall, time of sampling, state of the seas, and area 

weather conditions. 

Most stations were visited monthly, except for the years 1996 through 2000, when 

quarterly sampling occurred for University of Florida (UF) and Baywatch (BW) sites. 

On-site measurements were made using calibrated datasondes or individual test sets 

calibrated and maintained by RMA’s central laboratory. Chlorophyll and nutrient 

samples collected at University of Florida (UF) stations were sent to the UF professional 

laboratory. Other collected samples were returned to RMA’s central lab, the Bay County 

lab, or the Florida Department of Environmental Protection lab where trained personnel 

processed them using specialized equipment and standard protocol. The water quality 

data discussed in this report were collected between February 1990 and December 2006. 

Objective 

 This data analysis report was developed in contract between the RMA and the 

Northwest Florida Water Management District (NWFWMD). The contract specified that 

a scientist would be selected to complete an analysis of all Baywatch data from 1990 

through 2006. Subsequent reports will follow until 2010 for the purpose of further 

exploring the trends revealed in this cumulative data analysis. 

These analyses for the comprehensive Baywatch data set are intended to further 

the Program’s understanding of the St. Andrew Bay system and their Baywatch water 

quality monitoring program. It is the authors’ sincerest hope that the findings herein are 

valuable to the numerous volunteers and participants in this program over the years and 

that this may, in some small part, contribute to their vast and impressive effort.

Methods of Statistical Data Analysis 

Preliminary Database Reformatting 

Data review and formatting included alteration of the data set for analysis with 

Statistical Analysis Software (SAS Institute 2007, version 9.1). This formatting involved 

the removal of all data entries described as data not being required at the site, data not 

collected at a certain time for various reasons, and data that was lower than detection 

limits or beyond the capability of the sampling apparatus (e.g. a phosphorus 

concentration lower than the lowest detectable level or a Secchi depth greater than 5 feet 

when the depth was only 5 feet). Additionally, obviously erroneous data were omitted 

(i.e. pH of 81.0 or turbidity of 800.1 NTUs). Each of these entries were replaced by the 

typical “.” indicating missing data points to the software program. These omissions are 

revealed by inconsistent sample sizes in the data summary tables for the various 

parameters even within a given site. Parameters or entire sites were also omitted when 

scant data was available (n<10 for a parameter or entire site) at a site. Further, specific 

conductance was omitted due to its redundancy with salinity in the majority of sites. 

Site Statistical Summaries 

Preliminary analysis included descriptive statistics for all monitored sites (unless 

excluded as described above). Data statistical summaries were created by site (Results 

Tables 1-72). Stations have been described by current station number, former station 

number, and qualitative name or description, along with type of site (University of 

Florida Lakewatch sites and general Baywatch sites, and years sampled, followed by total 

years sampled. The data were summarized by water quality parameter including the 

sample mean, standard deviation as a measure of data variability, sample size for the 

parameter, range of measures for the variable (highest and lowest observations), and 

whether the data had a normal distribution which has implications for statistical 

evaluation methods (Shapiro-Wilks Normality Test, SAS, Inc. 2007). 

- 11 -
Statistical Differences 

Sites were evaluated by water quality parameter for statistically significant 

differences (General Linear Model, GLM on ranked data, SAS, Inc. 2007). Data were 

first examined for whether differences existed among sites (α=0.05) for each water 

quality parameter for currently monitored sites. In cases where statistically significant 

differences existed, multiple range comparison tests were performed to determine which 

sites were statistically distinct from each other (Student-Newman-Keuls Multiple Range 

Test, MRT on ranked data, SAS, Inc. 2007). This multiple range comparison allowed for 

viewing which sites specifically are statistically significantly different from one another 

and which are not statistically significantly different by parameter and site. Results will 

follow in Tables 73-99. 

Data Review by Percentiles and Correlation Analysis with Time 

In an effort to provide an ecologically focused depiction of the data, the data were 

reviewed by their placement within the context of the entirety of the data for each 

parameter. The central tendencies (means) were compared to the distribution of the data 

as revealed by percentiles (i.e. 90% of the data are less than this number, 25% of the data 

are less than that number). When the central tendency of a parameter for site was 

compared to these percentiles derived from pooling (a collection of all data across groups 

including UF and BW) all data, the results were presented in a spatial relationship. In 

these cases a site with a central tendency greater than the 90th percentile would indicate 

that its average measure was greater than 90% of all readings taken in this program over 

all years in data groups (UF and BW). The evaluation of the data via percentiles not only 

showed data placement relative to all the data for a given parameter combined, but also 

represented all data groups (UF and BW) in the same display. It was felt that this 

provided a more St. Andrew Bay-centered evaluation of the data that would better serve 

- 12 -
the purposes of this analysis than using State-wide water quality standards that have an 

inherent need to account for far greater variability among Florida waters. Site means for 

each parameter were examined where adequate (generally n>10) water quality data were 

available. 

Data found to fall in the data extremes were subjected to correlation analysis of 

the water quality parameter with time in cumulative days (modified Julian days) to 

illustrate trends in the data for that site over time. All correlation analysis results are 

presented, but statistically significant correlations (α=0.05) are shown in bold for 

emphasis (Spearman Correlation Analysis/, SAS, Inc. 2007). Results follow and are 

provided in Figures 9-18 and Tables 100-110. 

Results 

 Site statistical summaries, statistical differences, and evaluation by cumulative 

percentiles were created for all data groups. However, analysis of the data revealed 

further database reconciliation needs for the Seagrass data group sites. For this reason, 

these sites were subsequently removed from the results and will be provided with the 

seagrass monitoring data evaluation after the data has been reconciled with existing 

records. Complete results for University of Florida and Baywatch sites are provided 

below.

Discussion 

Preliminary Database Reformatting 

Ultimately, data used in the analysis included 42 University of Florida Lakewatch 

(UF) sites, 30 general Baywatch (BW) sites, and 24 Seagrass monitoring sites. However, 

due to database reconciliation issues the Seagrass site monitoring data was omitted from 

these results and this discussion. 

Site Statistical Summaries 

 Statistical summaries demonstrated variability among sites for almost all water 

quality parameters measured. The number of samples per site varied considerably as 

well. The data summary tables provide a robust summary of the sampling efforts over the 

years for these sites and parameters. The statistical summaries provided a thorough 

description of the data that allowed a careful examination of individual sites. The test for 

whether the data distribution fell in a normal “bell-shaped” curve (Normality) showed all 

parameters to be non-normally distributed in at least some cases. Therefore, the data were 

examined for differences using non-parametric techniques appropriate for these data. 

Statistical Differences 

The variability observed in the station summaries was evident in statistical 

differences among sites for almost all water quality parameters. Statistical differences 

were observed often within respective data groups (UF and BW). Differences were not 

found among sites for the parameters temperature (surface-UF and bottom -UF and 

bottom-BW). Differences were also not observed for pH (bottom-BW). All other 

parameters exhibited means separation (were different among sites) within each data 

group. This approach provided a depiction of data differences and similarities by the two 

data types, but not differences for the overall data (all sites together). 

- 134 -
Data analysis for differences among sites was performed on ranked data (number 

assignment by data value within the context of all data among sites) because of the nonnormal distribution of the data. The lower statistical power (ability to show statistical 

difference), inherent in non-parametric analyses, was overcome by the power provided by 

the robust data set collected by the Baywatch volunteers. This is evident in the relatively 

small differences revealed as statistically significant. This supported the assumption that 

data transformation was not necessary to achieve ample ability to demonstrate statistical 

differences among sites. However, high statistical power can, in some cases, fall short of 

demonstrating ecologically important differences among sites, despite its importance in 

showing the inter-site similarities and differences for monitoring purposes. 

Data Review by Percentiles and Correlation Analysis with Time 

In an effort to provide an ecologically focused depiction of the data, the data were 

reviewed by their placement within the context of the entirety of the data for each 

parameter. The central tendencies (means) were compared to the distribution of the data 

as revealed by percentiles (i.e. 90% of the data are less than this number, 25% of the data 

are less than that number). When the central tendency of a parameter for a site was 

compared to these percentiles derived from pooling (a collection of all data across groups 

UF and BW) all data, the results were presented in a spatial relationship. In these cases a 

site with a central tendency greater than the 90th percentile would indicate that its average 

measure was greater than 90% of all readings taken in this program over all years in both 

data groups (UF and BW). The evaluation of the data via percentiles not only showed 

data placement relative to all the data for a given parameter combined, but also 

represented both data groups (UF and BW) in the same display. It was felt that this 

provided a more St. Andrew Bay-centered evaluation of the data that would better serve 

the purposes of this analysis than using State-wide water quality standards that have an 

inherent need to account for far greater variability among Florida waters. 

Several areas of the St. Andrew Bay watershed repeatedly showed that they were 

out of synchronicity with the remainder of the bay. The Grand Lagoon area of St. 

Andrew Bay was routinely different than the remainder of the bay for its lower secchi 

- 135 -
depth measures, and its higher turbidity, nitrogen, and chlorophyll a, but most notably its 

higher total phosphorus measures. Powell Creek East was low for secchi depth and 

dissolved oxygen and high for turbidity, nitrogen and chlorophyll a relative to the whole 

of the data. Lake Powell was high for phosphorus, nitrogen, and chlorophyll a. The 

lower portion of Deer Point Lake had high levels of phosphorus. Water quality 

measurements taken in West Bay and its associated Crooked Creek and Burnt Mill Creek 

were higher for turbidity, chlorophyll and total phosphorus (West Bay only), and lower 

for secchi depth and dissolved oxygen (creeks only). Military Point was found to be 

relatively higher for total phosphorus when compared to the remainder of East Bay. 

North Bay was also relatively higher for turbidity compared to the rest of the bay. A 

number of bayous were also more often in the extremes of the data, including Lynn 

Haven Bayou (low secchi depth and dissolved oxygen, high turbidity), Beatty Bayou 

(low secchi depth, high turbidity), Mill Bayou (low secchi depth, high turbidity), Fannin 

Bayou (high turbidity), Posten Bayou (low secchi depth), Watson Bayou (low dissolved 

oxygen and secchi depth, high turbidity), Massalina Bayou (low dissolved oxygen and 

secchi depth), Johnson Bayou (low dissolved oxygen and secchi depth), Callaway Bayou 

(high turbidity). 

Evaluation of areas with means above the 90th percentile or the 75th percentile 

(below the 10th or 25th for Secchi depth, oxygen, or salinity) were further examined by 

comparing the parameter measures with time via correlation analysis. This was done to 

see if significant associations existed. If significant associations were found (in bold for 

emphasis with the figures) changes in the measures of the parameter over time could be 

viewed as increasing (positive “r”) or decreasing (negative “r”). This was less 

conclusive, but most parameters did have sites with significant correlations (associations) 

with time. One particularly noteworthy positive correlation with time was the association 

of total phosphorus with time in central Grand Lagoon (Grand Lagoon 3 and Grand 

Lagoon 4). Correlation analyses indicated that turbidity increased over time in the 

following areas: North Bay, Lower Fannin Bayou, West Bay, East Bay, Upper Johnson 

Bayou, and Powell Creek East. Secchi depth had a negative correlation with time 

(meaning water clarity has decreased over time) in Grand Lagoon (Grand Lagoon 1 and 

Grand Lagoon 2), Lower Crooked Creek, and Lower Posten Bayou. Dissolved oxygen 

- 136 -
levels decreased significantly over time in Johnson Bayou and Upper Watson Bayou. 

Additionally, there were several potentially improving areas for some parameters, 

including secchi depth in Upper Watson Bayou, Upper Massalina Bayou, Upper Burnt 

Mill Creek and Lower Warren Bayou. Dissolved oxygen levels improved over time in 

Massalina Bayou and Lower Watson Bayou. Nitrogen levels also improved over time in 

Lake Powell (Powell 1 and Powell 4). Understanding the circumstances surrounding 

changes in these water quality parameters at the select locations may prove beneficial to 

the Baywatch Program. 

Conclusions 

These data analyses each provided a distinct look at the St. Andrew Bay Resource 

Management Association’s cumulative data from their Baywatch Program for the years 

1990 to 2006. The statistical summaries provided a thorough description of the data that 

allowed a careful examination of individual sites. This showed the extremes of the 

variability in the data within each site. The site statistical differences showed inter-site 

variability by site type (UF versus BW). The high statistical power resulting from the 

large sample sizes caused small differences in water quality parameters to be statistically 

distinct in many cases. This approach provided a depiction of data differences and 

similarities by the two data types, but not differences for the overall data (all sites 

together). The evaluation of the data via percentiles not only showed data placement 

relative to all the data for a given parameter combined, but also represented both data 

groups (UF and BW) in the same display. Further examination for select cases of data 

extremes showed the influence of time on various water quality parameters. Although 

few significant trends were observed, potentially important associations of time were 

found with some parameters. Percentiles and correlation with time may prove to be a 

valuable approach to reveal ecological or system-wide importance. 

As stated in the objectives at the beginning of this report, these analyses for the 

comprehensive Baywatch data set are intended to further the Program’s understanding of 

St. Andrew Bay system and their Baywatch water quality monitoring program. It is the 

- 137 -
authors’ sincerest hope that the findings herein are valuable to the numerous volunteers 

and participants in this program over the years and that this may, in some small part, 

contribute to their vast and impressive effort and represent them well. 

Recommendations 

The Seagrass data should be reconciled with the data sheets to ensure accuracy and then 

subjected to statistical analysis. 

Statistically significant differences among sites provided somewhat limited insight into 

the data and repeating this analysis may not be of added value. 

Percentiles and correlation with time may prove to be a valuable approach to reveal 

ecological or system-wide importance and warrants repeating. 

Examination of specific water quality standard violations by parameter and site may be 

desirable to better understand the watershed’s status in terms of impaired waters as 

designated by the State of Florida. 

Evaluation of the sources of variability within the data, such as seasonal variation, 

freshwater inflow, rainfall, population etc., or the relationship between secchi depth and 

turbidity may provide a better understanding of some water quality parameters and 

should be explored.
